the same places; the characteristic cross-bands are easily seen on 

 the unpaired fins to a number of 5—10. 



At ca. 90mm and more the ground-colour is extremely 

 characteristic and surprisingly constant in the different speci- 

 mens. On the back and sides it has the dark-brown colour of the 

 Laminaria. Below a (broad) line from the anus to the upper corner 

 of the pectoral the abdomen is of a fine, dark, lemon-yellow colour 

 and the lower side of the head is a light flesh colour (below a line 

 from the corner of the gill-cover parallel with the free margin as 

 far as the mouth and under the lower jaw). The root of the pec- 

 toral is brown like the trunk, the outer part like the unpaired fins 

 and the ventral is light-red. The eye more golden than silvery, 

 the pupil black. The dark caudal cross-bands are now very distinct 

 on the fins, grading into the dark ground-colour on the caudal region. 



Regarding the differences between Liparis liparis and L. fabricii, 

 the pigmentation in L. liparis is very characteristic in the different 

 stages, as shown above, and the same holds good for L. fabricii (see 

 later). If we compare the 3 -|- 3 types described above of L. liparis, 

 i. e. 15, ca. 40 and ca. 90 mm, in regard to colour with similar individ- 

 uals of L. fabricii of ca. 20, ca. 50 and ca. 100 mm we obtain the fol- 

 lowing table.
